My son was diagnosed at five, having fought for two years to get his diagnosed, everyone though he was deaf as he did not seem to do as he was told. Although i know of people with Aspergers who were not diagnosed until 27 years old!

Everything that you describe of your son is typicaly indicative of Aspergers, they are usually very,fluent in language.Not really knowing what it means.Aspergers does not affect intelligence,and these children tend to be very bright and functional.They do talk inseccesantly,and loud noises ,esp ones are suprising frighten them and hurt them.Alarms, school bells, fire alarms etc...They repeat words or phrases over and over and have obsessions.The seem distant to the feeling of family or other peers and love being in thier own little world.This is because their brain has not developed to read facial expressions like you or i would,they cant tell when someone is angry or happy or sad.They cant hear intonation of voice either,so they tend to appear 'unemotional'.They can also be violent or aggressive.

Aspergers is 'High Functioning Autism'.And one of the ''Autistic Spectrum Disorders''.Although there are many types of autism. Not being sorry for his behaviour is also typical because is is not behaving badly,he is behaving as a child with Aspergers does. They also can not see other people perspective or point of view.Many children with ASD's get labelled 'bad' or 'disturbed children' when they are not.

All i can say that you can make sure that he gets all the support in school that he needs,it is hard being a parent with a child with and ASD, it is very hard!But there is support out there.If you know where to find it.

No one knows when it develops, but children are thought to have been born with it,it is NOT YOUR fault, as i thought my sons ASD was mine!It is incurable, but can be managed with therapies. If your son has problems sleeping like mine he takes Melatonin a natural hormone which children with ASD make very little of, so that really helps!He also wets the bed often, so he takes Desmopressan for that too.I also find that Omega3's and mixed Vitamins really help with his Hyperactivity.

As i said makes sure that you all get the help that you are enititled too and if you need support and info you can PM me too.
